There's no right way to do it, only ideas that are better than others in certain situations. But if you had the opportunity to head up the design of a new OS, one to Put Things Right, one that could be radical enough to varnish out those UI/X bumps that have clung on for years, but practical enough to be used every day, what would you design? How would you handle application management? What about file types and compatibility? Where would you cherry pick the best bits from other OSes and where would you throw away tradition? I've tackled this challenge for myself and present (an unfinished idea): KrocOS(warning: HTML5 site, will display without CSS in IE/older browsers). OSnews Asks: What would make your perfect OS?
